In "The Twilight Saga", the so-called imprint refers to an entangled emotion between a werewolf and his lover, which they call "imprint".
In other words, when a werewolf accidentally meets the other half of his life, he will automatically have a very strong emotion, which is beyond their own control. From then on, they will believe that This person will not marry other than this person, and he will always be by his side. No matter whether this person is in his old age or in his infancy, and whether the werewolf already has a lover, it will not hinder their emotions.

Extended information
In "The Twilight Saga: Breaking Dawn", the werewolves all had a branded lover, but Jacob did not have one at that time. The werewolf Jacob had a fiery chest and emotion. He has been guarding Bella silently like a knight, never leaving her, depending on her life and death.
There must be "love" between them, but this love cannot be called "love". As time passes, the gears of fate will eventually make him and Renesmee Cali Cullen become branded lovers.
As soon as Jacob saw Nice (the child's name), he fell deeply in love with her. The Italian vampires suspected that Nice was a vampire child (turned into a vampire as a human child), but Nice was not.
